Quality Control

Our 1H,1H-Perfluoropentan-1-Ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key specifications such as assay, water content, and impurity profiles. Our quality commitment ensures the material meets the stringent requirements for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for long-term stability, but the product can be stored at controlled room temperature (15-25°C) for short periods.
